To reset the clock on a 2002 VW Polo Playa, locate the clock adjustment button, which is usually near the radio or on the dashboard. If the trip meter button is stuck and won't turn, try gently wiggling it or using a small amount of lubricant around the base to loosen it. If that doesn't work, you may need to consult a mechanic or check the owner's manual for alternative reset methods. Alternatively, disconnecting the car battery for a few minutes may reset the clock as well.
